The dark side of curvature
2009
Geometrical tests such as the combination of the Hubble parameter H(z) and the angular diameter distance d(A)(z) can, in principle, break the degeneracy between the dark energy equation of state parameter w(z), and the spatial curvature Omega(k) in a direct, model-independent way. In practice, constraints on these quantities achievable from realistic experiments, such as those to be provided by Baryon Acoustic Oscillation (BAO) galaxy surveys in combination with CMB data, can resolve the cosmic confusion between the dark energy equation of state parameter and curvature only statistically and within a parameterized model for w(z). Combining measurements of both H(z) and d(A)(z) up to suffici…
"Por si las flais, ni flowers y en off": morphology of loanwords from english as idiomatic words in spanish idioms.
2020
En el presente artículo pretendemos ofrecer un análisis de la configuración formal de un tipo muy concreto de palabras idiomáticas: tres préstamos léxicos procedentes de la lengua inglesa que sobreviven insertos en locuciones españolas. Para ello, delimitaremos en primer lugar los conceptos de palabra idiomática, préstamo léxico y anglicismo. A continuación explicaremos el procedimiento metodológico para recopilar este tipo de piezas léxicas en dos diccionarios generales actuales del español, el DLE y el DEA, basado en el especial tratamiento lexicográfico que estas reciben debido a sus características, limitándonos a las unidades fraseológicas que conocemos como locuciones. Realizaremos un…
Maitrise de la fermentation butyrique par la microflore lactique réductrice
2018
Clostridium tyrobutyricum, bactérie anaérobie stricte, endosporulée, est à l’origine de l’apparition du défaut appelé «gonflement tardif » lors de l’étape d’affinage de nombreux fromages à pâtes pressées non cuites et cuites. Selon d’Incecco et al. (2018), elle passerait de l’état spore à un état de cellule végétative à la fin de l’étape d’acidification. Par ailleurs dans le projet ANR FoodREDOX, il a été montré qu’un ensemencement dans le lait d’une microflore abaissant le potentiel d’oxydoréduction, ralentirait la consommation de lactates et la production de butyrate par C. tyrobutyricum lors de l’affinage des fromages. Ainsi, connaître et comprendre les mécanismes de germination, sporula…
A probabilistic estimation and prediction technique for dynamic continuous social science models: The evolution of the attitude of the Basque Country…
2015
In this paper, a computational technique to deal with uncertainty in dynamic continuous models in Social Sciences is presented.Considering data from surveys,the method consists of determining the probability distribution of the survey output and this allows to sample data and fit the model to the sampled data using a goodness-of-fit criterion based the χ2-test. Taking the fitted parameters that were not rejected by the χ2-test, substituting them into the model and computing their outputs, 95% confidence intervals in each time instant capturing the uncertainty of the survey data (probabilistic estimation) is built. Using the same set of obtained model parameters, a prediction over …
Presentación del Monográfico: una mirada a la emigración española cualificada reciente: Estado de la cuestión y enfoques teóricos
2018
The study of qualified emigration has returned to the political and scientific agendas in recent decades. Currently the theoretical approaches have changed from a completely renewed economic, political, social and technological context. This article presents a summary of these new approaches and a current overview of skilled migration of Spaniards, based on a review of the specialized literature.
Three-dimensional rigid motion estimation using genetic algorithms from an image sequence in an active stereo vision system
2004
This paper proposes a method for estimating the three-dimensional (3D) rigid motion parameters from an image sequence of a moving object. The 3D surface measurement is achieved using an active stereovision system composed of a camera and a light projector, which illuminates the objects to be analyzed by a pyramid-shaped laser beam. By associating the laser rays with the spots in the two-dimensional image, the 3D points corresponding to these spots are reconstructed. Each image of the sequence provides a set of 3D points, which is modeled by a B-spline surface. Therefore, estimating the 3D motion between two images of the sequence boils down to matching two B-spline surfaces. We consider the…
Physics of agarose fluid gels: Rheological properties and microstructure
2021
Agarose, a strongly gelling polysaccharide, is a common ingredient used to optimize the viscoelastic properties of a multitude of food products. Through aggregation of double helices via hydrogen bonds while cooling under quiescent conditions it forms firm and brittle gels. However, this behavior can be altered by manipulating the processing conditions viz shear. For example, gelation under shear leads to microgel particles with large surface area, which in turn leads to completely different rheological properties and texture. Such fluid gels are shown to play an important role in texture modification of foods and beverages for dysphagia patients. In this study, different concentration of a…

Effectiveness of the Influence of Selected Essential Oils on the Growth of Parasitic Fusarium Isolated from Wheat Kernels from Central Europe
2021
The aim of the study was to determine the effectiveness of selected seven commercial essential oils (EsO) (grapefruit, lemongrass, tea tree (TTO), thyme, verbena, cajeput, and Litsea cubeba) on isolates of common Central European parasitic fungal species of Fusarium obtained from infected wheat kernels, and to evaluate the oils as potential natural fungicides. The study was conducted in 2 stages. At each stage, the fungicidal activity of EsO (with concentrations of 0.025
